Hey just wanted to say thank you to all the great persons behind this work! <3

My kindle has finally become useful :)

And fyi I can confirm the jailbreak works pretty fine with paperwhite 10th gen (pw4) with firmware 5.15.1 (I have been since years in flight mode to prevent updates ota, in the hope to find a jailbreak at some point xD )
